ABSTRACT:
A dry vibratable substantially alkali free refractory composition is disclosed for use as a disposable liner wherein the combination of a powdered metal utilized as a high temperature binder and an organic material utilized as a low temperature binder obviates the use of alkali oxides which previously caused degradation of the permanent refractory liner materials upon which the disposable lining was placed. Low density materials such as expanded inorganic materials can be added to the disclosed compositions to decrease the density. The invention also relates to a method of providing a disposable lining in a vessel having a permanent refractory lining, and to the resulting vessel thereof.
